We do not recommend applying more than one flea and tick treatment to your pet. If you choose to apply a different flea and tick product to your pet, we recommend bathing your pet in a detergent based dish soap and then waiting up to 48 hours before applying the new flea and tick treatment. If a pet is showing symptoms of hives, we recommend consulting with your veterinarian before applying a flea and tick treatment.

I guess you can. My dog doesn't wear a flea collar.

The Sentry shampoo is great for fleas & adding body to the coat and skin.  After trying others, I've stayed with Sentry for years. Once a week is fine. However flea control includes treating the yard as well if they are outdoor at times. Spraying the yard with Spectracide Triazicide once monthly will greatly improve flea control.  

For pets or humans who have a tick embedded in them buy a tick twister. They are less than $10 and very easy to use and there is no chance of it not working or the head getting broken of in the skin of you or your pet. You simply slide it on the tick and twist. It's such a tight fit the tick gets stuck in the twister so your not going to drop it or loose it in your home. We live on 60 acres in deer and dog tick heaven. Every pet and human big or small has gotten one on them and we use the tick twister every time. Not to mention my husband is a hunter so he gets them more than anyone. I ended up spraying his clothes with hunting tick repellant which has helped as well but our area is so over run with deer and ticks its crazy. Never saw a tick till I moved here, now it's no big deal.

Hi hailey237, 5 weeks old is still too early for your pup to bathe. The pup should be 8 weeks old.
